Creamy Sweet Potato Soup

It's finally starting to get chilly on the regular here in Boston, and I find myself craving the old standby soup and crusty bread dinner at least once a week. I had picked up a few sweet potatoes on a whim at the farmer's market last week so I browsed around the interwebs for some ideas and decided sweet potato soup was just the ticket.

Loosely based on Elise's sweet potato soup from an old issue of Bon Appetit and cut way down in proportions, this warm and faintly sweet bowl of yum was *almost* exactly what I was after. I didn't have any maple syrup, so I added a tiny bit of brown sugar, but I think I added too much. I'm leaving it off the ingredient list here, but if you taste yours and it's missing something, try sweetening it up a bit. Next time I think I will also add more aleppo pepper or red pepper flakes to up the spiciness, which I find myself enjoying more and more lately.

This was also my first attempt at using plain soy milk in cooking, but I thought it would work since soup is generally forgiving. The sweet potatoes add body and creaminess to the soup when blended anyway, so I didn't need to add much. As a result of that substitution, I find myself with one of the few truly vegan offerings in my humble vegetarian/vegan label. Sweet.

Sweet Potato Soup
adapted from Simply Recipes

2 tbsp olive oil
1/2 medium onion, chopped
1 lg celery stalk, chopped, leaves reserved for garnish
1 lg garlic clove, chopped
just over 1 lb sweet potatoes, peeled, cut into 1 inch chunks
2 cups vegetable broth or stock
1/4 tsp cinnamon
1/8 tsp aleppo pepper or crushed red pepper
1/8 tsp nutmeg
1/2 cup soy milk

Heat the olive oil in a medium sauce pot over medium-low heat. Add the onion, celery stalk, and garlic and saute until the onion is translucent, about 5 minutes. Adjust the heat down if necessary so the garlic doesn't brown. Add the sweet potato chunks, broth and spices and simmer over low heat, covered, until the sweet potato is tender all the way through, 15-20 minutes. Add the soy milk and taste, season with salt and pepper.

Turn off the soup and let it cool for 5-10 minutes before pureeing in batches in a blender. You could also use an immersion blender, if yours had not broken the second time you used it. Serve topped with chopped celery leaves

Serves 2-3


  1. Super interesting recipe .. I like the idea of soy milk, as it's often creamier and thicker than regular milk .. and also love, love, love the inclusion of celery leaves, in place of the usual parsley, etc.

    Also, just love your storytelling <3

  2. Sweet potatoes make a nice soup and I like the aleppo pepper and cinnamon in this one.
